Kinematics Question 47

Question: Assertion : Relative velocity of A w.r.t. b is greater than the velocity of either, when they are moving in opposite directions. Reason : Relative velocity of A w.r.t. B=vAvB

Options:

A) If both assertion and reason are true and the reason is the correct explanation of the assertion.

B) If both assertion and reason are true but reason is not the correct explanation of the assertion.

C) If assertion is true but reason is false.

D) If the assertion and reason both are false.

Show Answer

Answer:
